“…Regarding lichens as a source of pigments, to date, about 246 studies have been carried out, mainly focused on medicine, biochemistry, and genetics (Figure 2b). It has been discovered that the dyes produced by the symbiosis of lichens have specific chemical components with bioactive and antimicrobial capacity that are difficult to find in other natural sources; however, these metabolites may vary depending on the type and area of growth of the plant (Yamamoto et al, 2015;Yusuf, 2020). Although in the case of the Peruvian Geolashon scientific studies are limited (Figure 2c), it is known that T. flavicans contain secondary metabolites such as vicanicin that has antioxidant (Shameera Ahamed et al, 2019), antimicrobial, anticancer (El-Garawani et al, 2020) and antidiabetic (Maulidiyah et al, 2020b), which the industry can use.…”

Recently, interest in studying pigments from lichens has been aroused due to their bioactive properties and health benefits. The Geolashon (Teloschistes flavicans) is a thousand-year-old lichen from the Peruvian Andes characterized by its yellow filaments, traditionally used by the Peruvian inhabitants as a natural pigment for making handicrafts and medicinal purposes. In this sense, this article aims to compile all the studies on Geolashon as a source of natural yellow pigments, starting from its importance and applications by the Andean population to research on obtaining, characterizing, and properties of its extracts. Although studies on this lichen are limited, it was observed that the obtained from lichen are rich in 3-[1’-(2”,3”-dihydroxy-phenyl)-propyl]-7-hydroxy- chroman-4-one, vicanicin, parietin, other compounds and has antidiabetic, antibacterial, antileukemic, antimicrobial, anticancer and termiticide activity that would be interesting for use in the pharmaceutical, cosmetic, food and agricultural industries, generating added value in the final product. Aspects such as processing, functional properties, and toxicology of the bioactive components of Geolashon must be studied for its correct use.
